The objective of this systematic review was to assess whether a decrease in estrogen levels increases the risk of idiopathic condylar resorption by reviewing relevant literature and evidence. Material and Methods: This systematic review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A comprehensive search was performed in the PubMed (Medline), Science Direct (Elsevier), and Web of Science electronic databases. Results: The initial database search identified a total number of 453 studies. After applying the selection criteria, 36 articles were selected for a full-text analysis, and nine studies involving 1105 patients were included in the systematic review. According to the Newcastle\u2013Ottawa Scale (NOS), two of the included articles were graded as being of \u201cModerate\u201d quality and one was of \u201cFair\u201d quality. After evaluating the rest of the articles according to the AXIS tool for cross-sectional studies, we generally found that the reliability is moderate. The results show that the decrease in estrogen promotes the occurrence of inflammation in the temporomandibular joint, and some sources mention that it increases the occurrence of idiopathic joint resorption, but we did not establish a complete correlation between the level of estrogen and idiopathic joint resorption. Conclusions: This systematic review indicates that there is no evidence suggesting that fluctuations in estrogen levels contribute to idiopathic mandibular condylar resorption, but reduced estrogen levels can be associated with chronic pain in the temporomandibular joint.<\/jats:p>","DOI":"10.3390\/medicina61020201","type":"journal-article","created":{"date-parts":[[2025,1,23]],"date-time":"2025-01-23T12:24:09Z","timestamp":1737635049000},"page":"201","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Relationship Between Estrogen and Idiopathic Mandibular Condylar Resorption: A Systematic Literature Review"],"prefix":"10.3390","volume":"61","author":[{"given":"Benedikta","family":"Palesik","sequence":"first","affiliation":[{"name":"Department of Orthodontics, Lithuanian University of Health Sciences, LT-50106 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomas","family":"Musulas","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Lithuanian University of Health Sciences, LT-50106 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6215-9012","authenticated-orcid":false,"given":"Ar\u016bnas","family":"Vasiliauskas","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Lithuanian University of Health Sciences, LT-50106 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8025-9626","authenticated-orcid":false,"given":"Dainius","family":"Razukevi\u010dius","sequence":"additional","affiliation":[{"name":"Department of Maxillofacial Surgery, Lithuanian University of Health Sciences, LT-50106 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristina","family":"Lopatien\u0117","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Lithuanian University of Health Sciences, LT-50106 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,23]]},"reference":[{"key":"ref_1","first-page":"99","article-title":"Orofacial pain management: Current perspectives","volume":"7","author":"Uyanik","year":"2014","journal-title":"J.
